Quality Analysis 90/100
This denim is built for the long haul, featuring an extremely heavy 18oz Sasayama selvedge denim fabric and robust construction details like chain-stitched hems and hidden back pocket rivets, which significantly enhance tear resistance at stress points. The use of custom branded iron buttons further suggests a commitment to quality hardware over cheaper alternatives.
Comfort Assessment 50/100
This denim is made from 100% cotton, which offers a natural feel, but the 18oz weight and lack of stretch suggest a rigid, heavyweight garment that may restrict movement. The fit is described as a Slim Straight, which, combined with the heavy fabric, could feel restrictive.
Sustainability Impact 90/100
This denim is a sustainability standout, featuring homegrown Japanese cotton and dyed using Kuri Tamba, a natural dye derived from Tamba Chestnut skins, which are grown in the same area as the cotton. The entire process, from seed to stitch, is local to Japan, demonstrating a strong commitment to reducing transport emissions and supporting local agriculture.

Introducing the Shizen Selvedge Denim, the first collaboration between Samurai Jeans and Blue Owl. This collection combines Samurai's homegrown "Cotton Project" cotton with a range of natural overdyes, made exclusively for Blue Owl. Translated to "Splash", the Shibuki dye features the same Tamba chestnut dye found in the Kuri variant, with a lighter exposure resulting in a khaki-beige color. Dyed using Kuri Tamba, a dye derived from Tamba Chestnut skins. The chestnuts used to dye this fabric are grown in the same area as the cotton for this series.Grown, harvested, and woven in Japan, this collector's edition denim was originally conceptualized as a passion-project by Samurai Jeans founder Toru Nogami to produce a completely made in Japan denim from seed to stitch. Fittingly named the "Samurai Cotton Project," this 18oz selvedge denim sports a highly-visible slub and nep. The jeans come packed with symbolism referencing the brand's traditional warrior ethos including special edition iron buttons, jacquard pocket bags, back pocket rivets, and a custom co-branded leather patch.
